What is an NTC Thermistor?
Thermistors are temperature-sensing elements made of semiconductor
material that has been sintered in order to display large changes in
resistance in proportion to small changes in temperature. This
resistance can be measured by using a small and measured direct current,
or dc, passed through the thermistor in order to measure the voltage
drop produced. Thermistors are an incredibly accurate category of
temperature sensors. In general, thermistors are composed of sintered
ceramics consisting of highly sensitive material with consistently
reproducible properties of resistance versus temperature.
